Abstract: This document describes techniques and systems that enable user-equipment-initiated cancelation of a base station downlink transmission. The techniques and systems allow a user equipment (UE) to generate a downlink transmission cancelation request (DTCR) and send the DTCR to a base station to cancel or suspend an ongoing or scheduled downlink (DL) transmission from the base station. The UE can detect trigger events that can indicate that the DL transmission should be canceled or suspended. The UE can transmit the DTCR to the base station using a variety of techniques, including a physical uplink shared channel transmission or using a physical uplink control channel operation. These techniques allow the UE to cancel or suspend a DL transmission during the transmission or prior to a scheduled transmission, which can enable the UE to quickly mitigate adverse operating conditions such as excessive RF interference or low battery capacity.
